Description

Technical Field

[0001] This application relates to the field of flue gas analysis technology, and in particular to a multi-parameter, multi-channel portable flue gas analyzer. Background Technology

[0002] With increasingly stringent environmental regulations and rising demands for optimized industrial production processes, accurate, rapid, and multi-point monitoring of flue gas components emitted from stationary pollution sources has become crucial, in accordance with requirements such as the "Determination of Sulfur Dioxide from Stationary Sources by Constant Potential Electrolysis Method," "Determination of Nitrogen Oxides from Stationary Sources by Constant Potential Electrolysis Method," "Determination of Carbon Dioxide from Stationary Sources by Non-Dispersive Infrared Absorption Method," and "Determination of Carbon Monoxide from Stationary Sources by Constant Potential Electrolysis Method." Currently, most portable flue gas analyzers on the market employ a single-channel design, meaning they can only connect one sampling probe at a time to measure one sampling point. This prevents simultaneous measurement and comparative analysis of flue gas components at multiple spatial locations within the same timeframe, resulting in low detection efficiency and insufficient data accuracy. Furthermore, while multi-channel flue gas analyzers on the market can achieve multi-point or multi-gas measurements, they are bulky and cumbersome, typically requiring fixed installation in a single location, lacking portability and making them unsuitable for complex and variable industrial environments. Utility Model Content

[0003] This utility model proposes a multi-parameter, multi-channel portable flue gas analyzer. The present utility model provides the following technical solution for this purpose:

[0004] A multi-parameter, multi-channel portable flue gas analyzer includes a housing, a cover, a cooling fan, and a flue gas analysis channel. The flue gas analysis channel includes a flue gas filter tube and a flue gas analysis module. The housing and cover are hinged together, and a cooling fan is installed on the side wall of the housing. The housing contains a top plate, a middle plate, and a bottom plate, which are sequentially and fixedly connected. The flue gas filter tube is installed on the top plate, and a water-gas separation filter element and a polymer filter element are sequentially arranged inside it along the flue gas flow direction. The flue gas analysis module is installed on the middle plate, and a notch is provided on the top plate for the corresponding flue gas analysis module. The flue gas analysis module includes a housing, a display screen, a flue gas path pipe, a sensor, a gas path extraction module, and a control module. The display screen window is located on the outer surface of the top plate. The flue gas path pipe and the control module are located inside the housing. The inlet of the flue gas path pipe is connected to the outlet of the flue gas filter tube, and the gas path extraction module and the sensor are sequentially connected in series along the flue gas flow direction in this gas path pipe. The display screen and the sensor are both electrically connected to the control module. The combination of multi-stage flue gas filter elements and multiple sensors effectively removes impurities from flue gas and accurately detects various gas components; the top plate, middle plate and bottom plate are fixedly connected in sequence to form a stable multi-layer support structure, which makes the flue gas filter components and analysis modules reasonably distributed, thereby effectively reducing the overall size of the equipment and improving space utilization and portability.

[0005] Furthermore, the flue gas analysis channels are configured with multiple groups, each capable of independently completing flue gas sampling and analysis tasks. This multi-channel design allows for simultaneous measurement and comparative analysis of flue gas components at multiple sampling points, significantly improving detection efficiency and data analysis accuracy.

[0006] Furthermore, the sensors include, but are not limited to, sulfur dioxide sensors, oxygen sensors, carbon monoxide sensors, nitric oxide sensors, nitrogen oxide sensors, hydrogen sulfide sensors, pressure sensors, and temperature sensors.

[0007] Furthermore, the flue gas pipeline is equipped with a cleaning interface, which can be connected to a self-priming cleaning pump for cleaning the flue gas pipeline and sensor detection end, thereby reducing the impact of impurity residue on detection accuracy and extending the service life of the equipment.

[0008] Furthermore, the bottom of the enclosure is equipped with lockable omnidirectional casters, and a telescopic rod is provided on the side wall of the enclosure opposite the installation position of the casters. With the cooperation of the omnidirectional casters and the telescopic rod, the equipment can be moved in the industrial site.

[0009] Furthermore, the four corners of the middle plate, bottom plate, and top plate are respectively equipped with silicone elastic pads for shock absorption, which are used to reduce the vibration transmitted to the internal components when the enclosure is moved or subjected to impact.

[0010] Furthermore, the top plate is equipped with clamps for holding the flue gas filter tube, which can be disassembled to facilitate filter element replacement and maintenance.

[0011] Furthermore, the base plate is equipped with lithium batteries and a charging interface. Multiple lithium batteries are connected to the power control assembly system via electrical cables for reasonable charging. The charging interface is electrically connected to the lithium batteries through the power control circuit, enabling the equipment to continue working even without an external power source.

[0012] Furthermore, a cooling fan control switch is provided on the top plate. The cooling fan control switch is electrically connected to the control module, which provides the ability to manually intervene in heat dissipation and enhances the equipment's adaptability to high-temperature environments.

[0013] Furthermore, it also includes a power plug and a power control circuit. The power plug is located on the side wall of the enclosure, and the power control circuit is located on the bottom plate. The power plug is connected to the power control circuit through a charging interface. The power control circuit monitors battery parameters in real time and automatically cuts off the power when triggered to avoid damage to the lithium battery.

The control module is electrically connected to the display screen 92 and the sensor 94 to collect, process, and display flue gas analysis data. In addition, the control module includes a data storage unit and a wireless communication module; the data storage unit records the detection data from the sensor 94; the wireless communication module transmits the detection data and equipment status information to an external terminal or cloud server. Furthermore, the flue gas analysis channels are configured with multiple groups, each capable of independently completing flue gas sampling and analysis tasks.

[0031] The implementation process of a multi-parameter, multi-channel portable flue gas analyzer according to an embodiment of this application is as follows: After the user moves the portable multi-channel flue gas analyzer to the target location, opens the case cover and turns it on, multiple sampling lines are connected to different flue gas analysis channels to achieve simultaneous measurement of flue gas components at multiple spatial points. The flue gas in each channel enters the flue gas path pipeline after passing through a water-gas separation filter and a polymer filter. The gas path extraction module draws the flue gas from the inlet to the sensor detection area. The sensor detects the flue gas components and transmits the signal to the control module. The control module processes the received signal and displays the analysis results in real time on the display screen. After the gas test is completed, the self-priming cleaning pump is turned on to discharge the residual gas through the internal gas path.
